THE MOTIVATIONAL DYNAMICS OF EFL TEACHERS: GOAL-SETTING, INTRINSIC INTEREST, AND TEACHING EFFECTIVENESS

The prominence of teacher motivation in teaching practices and behaviors and its impact on student achievement is widely recognized in educational psychology. Nevertheless, English as a foreign language (EFL) teachers’ motivation and the factors influencing its development appear an uncharted domain. The following study attempted to explore EFL teachers’ motivation in relation to intrinsic interest, goal setting, and teaching effectiveness. The sample comprised 127 Iranian EFL teachers with their students (N= 500). The teachers were asked to complete a battery of two questionnaires. To assess teacher goal-setting and intrinsic interest, the researcher utilized the 'Teacher Self-Regulation Scale (TSRS)' designed   by Yesim, Sungur, and Uzuntiryaki (2009). To gauge teacher motivation, 'The Work Tasks Motivation Scale for Teachers' designed by Fernet (2009) was employed. In the present study, this questionnaire was translated to Persian and then the translated version was validated in the Iranian context to pave the way for future studies on teacher motivation in Iranian context. To measure language teachers' performance and success in language teaching, the researcher employed the 'Characteristics of Successful Iranian EFL Teachers Questionnaire' (CSIET) designed and validated by Moafian and Pishghadam (2009). The results of structural equation modeling (SEM) indicated that there were relatively strong interrelationships among the three variables (intrinsic interest, goal-setting, and job motivation). All of them were positive and significant predictors of teacher success, and intrinsic interest exhibited the highest impact. It was also found that intrinsic interest positively influenced job motivation. The SEM analysis also indicated that go  Article visualizations: al-setting was positively influenced by both intrinsic interest and job motivation

FREQUENCY AND PREDICTOR FACTORS OF IRREVERSIBLE PULPITIS

Abstract. Objective: Referral pains are one of the most common challenges which dentists are faced with them during diagnosis and before treatment. Pain referral can take place in tooth and other craniofacial structures and influence the diagnostic process. The present study was accomplished to evaluate the prevalence of irreversible pulpitis in patients refferd to Endodontic department of dental school of shahid Sadoughi University in 2017 with chief complaint of pain. Methods: This study is a descriptive and cross-sectional type of study conducted on 100 patients(21 males and 79 females) refferd to Endodontic department of dental school of shahid Sadoughi University in 2017 with chief complaint of pain.Informed consent was taken from patients. Data obtained from medical history, dentistry history, clinical examinations, and radiography were recorded in questionnaire developed for this purpose. Finally, the data were analyzed using SPSS18 software, Chi-square and Fisher exact test. Results: In the present research, the prevalence of irreversible pulpitis was obtained to be 77%. This prevalence in female was significantly more than males (P-value = 0.021). Patients with irreversible pulpit significantly reported more severe pain (p-value=0.000) and pain at the real site (p-value=0.028).The frequency of irreversible pulpitis showed no significant correlation with age and type of pain (P-value<0.05). Conclusion: Considering the findings of this research, the prevalence of irreversible pulpitis in patients refferd to Endodontic department of dental school of shahid Sadoughi University in 2017 with chief complaint of pain was three times more than that of other diseases. This frequency showed significant relationship with factors of gender, pain severity, and the pain feeling site.Keywords: Irreversible pulpitis, pain, root canal treatment

Mutations in GJB2 as Major Causes of Autosomal Recessive Non-Syndromic Hearing Loss: First Report of c.299-300delAT Mutation in Kurdish Population of Iran.

BACKGROUND AND OBJECTIVES: Autosomal recessive non-syndromic hearing loss (ARNSHL) with genetic origin is common (1/2000 births). ARNSHL can be associated with mutations in gap junction protein beta 2 (GJB2). To this end, this cohort investigation aimed to find the contribution of GJB2 gene mutations with the genotype-phenotype correlations in 45 ARNSHL cases in the Kurdish population. Subjects and. METHODS: Genomic DNA was extracted from a total of 45 ARNSHL families. The linkage analysis with 3 short tandem repeat markers linked to GJB2 was performed on 45 ARNSHL families. Only 9 of these families were linked to the DFNB1 locus. All the 45 families who took part were sequenced for confirmation linkage analysis (to perform a large project). RESULTS: A total of three different mutations were determined. Two of which [c.35delG and c.-23+1G>A (IVS1+1G>A)] were previously reported but (c.299-300delAT) mutation was novel in the Kurdish population. The homozygous pathogenic mutations of GJB2 gene was observed in nine out of the 45 families (20%), also heterozygous genotype (c.35delG/N)+(c.-23+1G>A/c.-23+1G>A) were observed in 4/45 families (8.8%). The degree of hearing loss (HL) in patients with other mutations was less severe than patients with c.35delG homozygous mutation (p<0.001). CONCLUSIONS: Our data suggest that GJB2 mutations constitute 20% of the etiology of ARNSHL in Iran; moreover, the c.35delG mutation is the most common HL cause in the Kurdish population. Therefore, these mutations should be included in the molecular testing of HL in this population. KEYWORDS: Autosomal recessive non-syndromic hearing loss; Gap junction protein beta 2; Hearing los

Evaluation of comparative advantage on production and export of saffron

With due attention to facilities, and different potentials and sources in agriculture of Torbat Heydarieh city, this region is suitable for cultivation and production of saffron. In this study comparative advantage of saffron production in Torbat Heydarieh investigated using DRC index and policy analysis matrix (PAM) during 2012-13. Also in this study evaluated comparative advantage of saffron export using RCA and RSCA index. The Results showed that saffron production in Torbat Heydarieh has a comparative advantage. According to the NPC price index is higher than market price and so producers benefited from subsidies and market support. According to the EPC standard, government interventions has a positive effect on production of this crop, so was supported from input and production markets this crop. In result, NSP index was positive in all sectors. Results of these two indexes showed that Iran, Spain and Greece had preferences on export relative advantage in the world during 2004-2012. While value added of Iran saffron export is not considerable, therefore, for improving this condition, joining Iran to the WTO in order to reduce tariffs on exports, paying more attention in marketing and supplying necessary facilities such as foreign exchange support in the country was suggested

Pricing strategies of saffron: strategic factors analytical

Saffron is considered as an important crop for farmers of the Khorasan Razavi province due to the ability to create high employment and generate appropriate income. Problems of saffron producers in marketing and export has caused this product not to be in a good position in the world market despite its high quality. Therefore, the study of marketing mix as one of the most important factors affecting marketing of saffron in the region seems to be necessary. In order to identify the strengths, weaknesses, opportunities and threats of marketing mix of saffron, a strategic factor analysis approach was used in this study. The required information was collected through face-to-face interviews and completing a questionnaire with managers and experts of saffron producing and exporting companies in Mashhad and Torbat Heydarieh cities in 2015. To investigate the validity of the questionnaire, the questionnaires were reviewed by supervisors and consultants and several experts. At first, some initial questions were completed and using the Cronbach's alpha method, the reliability coefficient was 0.79. The results of the internal factor matrix showed that the weaknesses overcome the strength and, according to the results of external factors matrix, the points of opportunity are superior to the threat. The results of the study showed that the increase in the value added due to saffron processing with a score of 0.57 and export value with a score of 0.54 are the most important strength and low purchase price of farmers with a score of 0.13 and a lack of knowledge of the price of competitors with a score of 0.11 are the most important weaknesses in marketing mix price. Also, the export of the product with different qualities based on the financial ability of target customers with a score of 0.32 and price determination based on the competitive and economic environment with 0.23 are most significant opportunities, and the volatility of the exchange rate with a score of 0.4 and a price fluctuation in the export market with a score of 0.36 are the most important current threats of saffron marketing. The general results obtained from the status analysis matrix indicate that the saffron processing factor strategies are defensive. Therefore, according to the results, the strategies of establishing a regional exchange market for saffron and long-term control of prices in export markets with the aim of paying attention to pricing and fair purchase are suggested
